These data are modeled on the results of the National Educational Assessment tests of 4th and 8th graders in the United States, which, due to COVID, was only recently given again (2022) after a 3-year gap (last given in 2019)
District: The school districts in your state, by ID code
Region: N=North or S=South
% poverty:the percent of families in the school district living below the poverty line, in three groups -- Less than 10%, 10 to 24%, or More than 25%. Higher percentages mean poorer districts, on average.
Issued Chrome books to all students:During the pandemic, all school systems provided at-home instruction via the internet. To facilitate this, many districts provided home computers in the form of Chrome books to all students. The state even offered to funding for the purchases in the poorest districts.
The data file also includes 4 score reports. These represent, for each district, the average scores of all students at both grade levels (4th and 8th), in 2022 and 2019. As you see, the test comes in two sections -- Math and English.
Math Scores 2019
English Scores 2019
Math Scores 2022
Math Scores 2022
You decide to ignore the "minimal acceptable average" standards but test directly whether there has been a significant change in the scores from 2019 to 2022. For Math, there has been a drop of a little over 5 points on average -- if this change represents a significant difference in student performance statewide, please provide the numeric evidence (p-value) supporting this finding to 12 digits
